WIRE FOR CHECK-ROW CORN-'PLANTERS.

SPECIFICATION forming part of Letters Patent No. 328,452, dated-October 20. 1885- Application filed August 10, 1885.

T 0 all whom it may concern.-

Be it known that I, JOSEPH O. BARLOW, of Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in WVire for Check-Row Corn- Planters; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the figures an] letters of reference marked thereon.

This invention pertains to certain improvements in the construction or form of what are technically known as knots, attached to or forming part of the check-row wire,and serving to actuate the planting mechanism; and it consists in the novel method or manner of twisting or laying the wire composing the knot, whereby a firm and durable knot is formed, and the cutting or wearing of the fork or other portion of the planting mechanism with which the wire co-operates is prevented, thereby diminishing the wear upon the machine, and at the same time increasing the life of the knots, all as hereinafter more fully de scribed, and pointed out in the claims.

In the accompanying drawings,wherein one mode of carrying into execution my said invention is illustrated, Figure 1 represents a section of a check-row wire, showing how the knots have heretofore been formed and applied. Fig. 2 illustrates my improved form of knot as applied to the joint or coupling between the ends of adjacent wires or sections.

Similar letters of reference in the several figures denote the same parts.

Check-row wires as heretofore generally constructed have been made from sections of wire A, Fig. 1, united by bending the wires to form interlocking eyes or loops A,and coiling the ends back from the eyes or loops and around the body of the wire, as shown at A When so constructed the extreme ends a of the wires stand out more or less from the body of the wire, forming salient points or projec- Serial No. 174,012.

tions, which, striking against the fork of the 4 actuating devices on the planter, are not only worn themselves or are caught and bent or deflected, so as to injure the connection at that point, but they also produce an excessive wear of the fork or equivalent actuating device.

To overcome these defects in the construction of the knot, as shown in Fig. 1, instead of carrying the end of the wire forward and leaving the point lying upon and projecting from the body of the wire, as in Fig. 1, I carry the end back or in the opposite direction, and wind it upon the first coil, asshown at A, Fig. 2, and press the extreme end or point a down in rear of the preceding coil a,whereby the knot is not only enlarged and the connection strengthened, but the end or point a of the wire is shielded by the preceding coil of wire,which makes contact with and actuates the fork. In this manner not only am I enabled to construct a more firm and durable knot, but one less subject to be injured by or inflict injury upon the fork or equivalent device for operating the planting mechanism.

Having thus described my inventi0n,I claim as new 1. An improved knot for check-row wires, formed by coiling the wire composing theknot back upon itself, substantially as described.

2. The improved knot for check-row wires, composed of a primary coil and a reversclywound external coil, substantially as described.

3. The herein-described improved knot and coupling for check-row wires, composed ofthe eye or loop, and the primary and reversed coils, the latter being formed by first wrapping the end of the wire around the body,and then back upon the coil so formed, substantially as described.

JOSEPH O. BARLOWV.
